File makedumpfile-call-open_dump_bitmap-after-initial.patch of Package makedumpfile

Subject: move call to open_dump_bitmap() to after call to initial()
References: bsc#992885

When open_files_for_creating_dumpfile() is called, we don't have all
necessary information to determine whether a bitmap file is actually
needed. In particular, we don't know whether info->flag_cyclic will
ultimately be set. This patch moves the call to open_dump_bitmap()
to after initialize() when all flags are known.

For the dump_dmesg() path, no bitmap file is needed.
